Former xAI co-founder launches River AI to build personalized AI you actually own

Igor Babuschkin, who co-founded Elon Musk’s xAI, has stepped out on his own. His new venture, River AI, is betting that the future of artificial intelligence isn’t about one model to rule them all. It’s about giving individual users AI systems they can shape, own, and align with their own values.

Babuschkin announced River AI on April 20, and the company is already generating serious investor interest. As of mid-May, River AI is in discussions to raise as much as $1B in funding at a potential $5B valuation. General Catalyst is reportedly in talks to lead the round, and Babuschkin himself plans to invest up to $100M of his own money.

The pitch: AI that works for you, not a corporation

River AI’s core thesis is a direct challenge to how AI is currently built and deployed. Today’s dominant models, whether from OpenAI, Google, or Anthropic, are corporate products. They’re trained on centralized datasets, tuned to corporate safety policies, and delivered as services you rent rather than own.

River AI wants to flip that. The company is focused on building personal AI systems where users have genuine sovereignty over how their AI behaves.

The specifics of how River AI plans to deliver on this vision remain unrevealed. There’s no public product yet, no technical whitepaper, and no demo to scrutinize. What exists right now is a thesis, a team with serious credentials, and a very large pile of potential capital.

Why the timing matters

Babuschkin’s departure from xAI fits into a broader pattern that’s been reshaping the AI industry. Engineers, researchers, and executives from OpenAI, DeepMind, Google, and now xAI have been spinning up their own companies at an accelerating pace.

xAI itself was founded by Musk in March 2023 as an alternative to what he viewed as overly cautious, politically biased AI development at companies like OpenAI. xAI underwent significant restructuring in early 2026 when it integrated into SpaceX, a transition that coincided with the departure of multiple co-founders and key staff.

What this means for investors

Every major AI lab already offers some degree of customization. OpenAI has custom GPTs. Anthropic lets enterprise clients fine-tune Claude. Google has been building personalization into its Gemini products. River AI isn’t entering an empty field. It’s entering a field where the incumbents have billions of dollars in infrastructure and years of iteration.

The $5B potential valuation is aggressive by any standard for a pre-product company. Babuschkin’s willingness to put $100M of his own capital on the line suggests he’s aware of the cost.
